# BSRN NSRDB PSM v4 aggregated
Point-extracted [NSRDB (National Solar Radiation Database)](https://nsrdb.nrel.gov/) PSM v4 (aggregated variant) data for [Baseline Surface Radiation Network (BSRN)](https://bsrn.awi.de/) stations.
## Dataset Description
Each file contains 30-minute NSRDB variables at a single BSRN station location. **Extraction is performed via the NREL NSRDB API (NLR)**. The `aggregated` variant (v4.0.0) provides **4 km spatial resolution** and covers the Contiguous United States and other regions using the GOES archive from **1998 to 2024**.
### File Structure
Station folders use the **lowercase** BSRN three-letter code (e.g. `ber`).
```
{station}/
{station}{MM}{YY}_nsrdb_aggregated.parquet # One file per month
```
Example:
- `ber/ber0198_nsrdb_aggregated.parquet` — BER, January 1998
### Variables
| Column | Description | Units |
|-----------|----------------------------------|---------------|
| ghi_nsrdb | Global Horizontal Irradiance | W/m² |
| bni_nsrdb | Beam Normal Irradiance (DNI) | W/m² |
| dhi_nsrdb | Diffuse Horizontal Irradiance | W/m² |
- **Index**: UTC `DatetimeIndex` (30-minute resolution).
- **Time coverage**: NSRDB PSM v4 `aggregated` variant spans 1998–2024.
## Usage
### Load from Hugging Face
```python
from huggingface_hub import hf_hub_download
import pandas as pd
# Download a single file; path is {station}/{station}{MM}{YY}_nsrdb_aggregated.parquet
path = hf_hub_download(
repo_id="dazhiyang/bsrn-nsrdb-aggregated",
filename="ber/ber0198_nsrdb_aggregated.parquet",
repo_type="dataset",
)
df = pd.read_parquet(path)
# df has DatetimeIndex (UTC) and columns: ghi_nsrdb, bni_nsrdb, dhi_nsrdb
```
### Use with bsrn package
The `bsrn` package can fetch NSRDB data from Hugging Face **into RAM** (no disk cache) automatically.
```python
from bsrn.io.nsrdb import add_nsrdb_columns
# Add NSRDB columns to an existing BSRN DataFrame
df = add_nsrdb_columns(df, station_code="BER", variant="aggregated")
```
